I completely understand your reasoning! Thanks for taking the time to read my comment and I appreciate the reply! :)
I think your English is good and I understood everything in the game! I noticed a few minor typos (such as Axel saying "Hey gus!" instead of "Hey guys!" when you first meet him at the colosseum), and the dialogue came across as stilted at times (i.e. the English was grammatically correct but quite formal for speech), but again it was perfectly understandable and conveyed the right emotions! The dialogue reminded me a lot of old RPGs since the writing feels similar in those, which I personally thought added charm to it!
I hope the rest of your day (or night) goes well!
